Longtime Red Hot Chili Peppers drummer Chad Smith sat in with Levon Helm this past Saturday. The drummer attended one of Helm’s Midnight Rambles as a fan and emerged partway through the Levon Helm Band’s set for on “All on a Mardi Gras Day” and “The Weight.” Smith—who has played with the Chili Peppers since the late 1980s—is currently touring with his instrumental funk side-project Chad Smith’s Bombastic Meatbats.
